[SoftwareControlledHamRadio] The T41 from 4SQRP and V11 boards.
¿ªÔÆÌåÓýHi Harry, Thanks for the note. ? I just checked my records and I sold a total of 218 full sets of V10/V11 boards (plus odds and ends of full sets).? But that was two plus years ago.? I may still have sets of V10/V11 bare boards in the recycle box¡ I¡¯ll dig around to see if I can find some for you because the demand for the V10/V11 sets has dried up as of the V12 release.? In any case, the GERBERS for the V10 and V11 boards are all available at no cost on my GITHUB.? The 4SQRP boards (+GERBERS) are not available to me so I can¡¯t support them as of now. ? Beyond that, I¡¯ve sold 1,200+ sets of V12, and 150+ in stock that I will sell at Hamvention in about a month.? Last year I sold 200 sets at FDIM and HamVention alone in just 4 days, and I expect to do that and more this year, since I now have an inside booth (4111 for those who will attend). ?I will take paper orders if I run out (I expect that will happen because I only have so much space in my luggage).? I will also be selling the latest T41 book (signed copies) from Jack and Al at Hamvention in my booth (NOT at FDIM where Jack and Al will be selling the book). ? I won¡¯t be able to support older versions of the T41 past free GERBERS and documentation.? The cost of doing so is prohibitive.? I have thousands of US dollars tied up in parts and boards¡ and can only support so much.? I don¡¯t know if Greg supplies boards for your V10/V11 projects or not¡ I don¡¯t really follow what he does (and hence can¡¯t/ don¡¯t/ won¡¯t comment on it). ?I do see some new directions on the horizon for the T41 after V12.? The RF performance is outstanding¡ now to supercharge the user interfaces and the I/Q processing parts. ? ? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ ?

I suppose that Andy G8HCK passed on my inquiry to him for a couple of V10/V11 QSE PCBs and you may be wondering why I¡¯m looking for such old technology.? I¡¯ve been using my original V10 QSE board so much for hardware development that it is starting to fall apart with all the cut traces, solder jumpers and extra mounting holes.?? Fortunately, it still works in its original form. For my purposes, the V12 RF boards are too dense for much hardware experimentation, particularly with 4 layer boards.?? I feel that they don¡¯t encourage the original ¡°EP¡± concept that Jack and Al first promoted.? I see the V12 concept as almost a pre-production prototype for a commercial radio with very tight specs.? I really admire the way that your team are striving to make it all work and I wish you all every success. My T41 interests now lie in the direction which Greg KF5N is taking both for hardware and software development.? Of course it is a positive sign of an on-going healthy project like the T41-EP that it can and does evolve in several directions and long may that continue ! 73 Harry GM3RVL |
